Scaffolding system and method for producing said scaffolding system

ABSTRACT

The invention relates to a scaffolding system with at least one scaffold decking (30). The scaffold deckings (30) preferably have identical fittings (10) which are connected to decking profiles (32) of different heights, in particular in an identical manner. Particularly preferably, the scaffolding system has at least two scaffolding deckings (30), each having identical fittings (10) but decking profiles (32) with different maximum heights (H32), wherein further preferably the length (L32) of the decking profile (32) with lower maximum height (H32) is shorter than for the decking profile with higher maximum height (H32). In a further preferred embodiment of the invention, the scaffolding system comprises at least three scaffold decks (30), each having identical fittings (10) but decking profiles (32) with different maximum heights (H32), wherein further preferably the decking profiles (32) are of different lengths and have greater maximum heights (H32) with increasing length (L32).

INVENTION BACKGROUND

The invention relates to a scaffolding system according to the genericterm of claim 1. The invention further relates to a method formanufacturing such a scaffolding system.

It is known to provide scaffolding systems, especially working andfacade scaffolding systems, with a certain load class. Such scaffoldingsystems comprise in particular several scaffold deckings. The knownscaffold deckings of a load class have decking profiles of the sameheight. The height of the decking profiles corresponds to the height ofthe fittings of the scaffold deckings connected to the decking profilesin each case. The height of the decking profiles is generallyindependent of the length of the scaffold deckings. However, since theload capacity of the scaffold deckings depends on the length of therespective scaffold deckings, short scaffold deckings are oversizedcompared to long scaffold deckings with the same height of the deckingprofiles.

OBJECT OF THE INVENTION

It is therefore the object of the invention to provide a scaffoldingsystem and a method for manufacturing this scaffolding system, wherebythe scaffolding system can carry loads particularly effectively and atthe same time can be finished in a simplified manner.

DESCRIPTION OF THE INVENTION

This object is solved according to the invention by a scaffolding systemaccording to claim 1 and a method for manufacturing this scaffoldingsystem according to claim 14. The subclaims give preferred embodiments.

The designations “height”, “length”, “width”, “top”, “bottom”, etc.refer to the assembled state of the scaffolding system.

The scaffolding system can include only the first scaffold decking oradditional scaffold deckings.

The object according to the invention is thus solved by a scaffoldingsystem with a first scaffolding decking, wherein the first scaffoldingdecking has a first decking profile for supporting a walkable firstdecking panel and a first fitting for connecting the first scaffoldingdecking to a first horizontal ledger. The first fitting comprises aone-piece first fitting body fixedly connected to the first deckingprofile. The maximum height of the first decking profile exceeds themaximum height of the first fitting body, in particular by a factor maxKh=1.5 to 2.5.

According to the invention, it is thus provided that the first scaffolddecking has a fitting for reversibly releasably connecting the firstscaffold decking to a first horizontal ledger. The height of thisfitting (in the vertical direction) is less than the height of the firstdecking profile, which is preferably non-detachably connected to thefirst fitting. In this way, the first scaffold decking is suitable forcarrying large loads and can still have a standardized first fitting.

Preferably, the first fitting body is made of sheet metal. This enablesparticularly simple and cost-effective production.

The first fitting body can have two corner areas, each with surfacesbent at right angles, on which the first decking or covering profilerests in sections. This ensures particularly reliable load transfer fromthe decking profile to the fitting.

The first scaffold decking can have an anti-lift device. The anti-liftdevice preferably has a bracket that can be moved relative to thefitting body to engage under the first horizontal ledger.

In a preferred embodiment of the first scaffold covering, the firstdecking profile is attached to the first fitting body with at least oneL-shaped screw, rivet, tox and/or welded connection. Such a weldedconnection enables reliable and simple fabrication of the first scaffolddecking.

Particularly preferably, the underside of the first decking profile isrounded towards the first fitting. Notch stresses in the area of theunderside of the first framework covering can thus be avoided.

The advantages of the invention are particularly evident in a previouslydescribed scaffolding system with a second scaffold deck, the secondscaffold decking having a second decking profile for supporting awalkable second decking and a second fitting for connecting the secondscaffold decking to a second horizontal ledger, the second fittinghaving a one-piece, i.e. integral, second fitting body firmly connectedto the second decking profile, the second fitting being of the samedesign as the first fitting and the maximum height of the second deckingprofile being lower than the maximum height of the first deckingprofile, the second fitting having a one-piece second fitting bodyfixedly connected to the second decking profile, the second fittingbeing of the same design as the first fitting and the maximum height ofthe second decking profile being lower than the maximum height of thefirst decking profile. Preferably, the factor mid Kh is equal to 1.1 to1.5. In this way, decking profiles of different heights can be used withidentical, in particular identically designed, fittings and canpreferably be connected in an identical manner (bolting, riveting,toxing and/or welding).

Particularly preferably, the second lining profile is shorter than thefirst lining profile. The second, shorter lining profile then has alower lining profile height than the first lining profile. In otherwords, the second, shorter, decking profile is thus not oversized andcan be formed more easily.

Further preferably, the scaffolding system comprises a third scaffolddeck, the third scaffold decking comprising a third decking profile forsupporting a walkable third decking and a third fitting for connectingthe third scaffold decking to a third horizontal ledger, the thirdfitting comprising a one-piece third fitting body fixedly connected tothe third decking profile;

wherein the third fitting is formed the same as the second fitting andthe maximum is height of the third decking profile is lower than themaximum height of the second decking profile.

The maximum height of the third decking profile can be matched to themaximum height of the third fitting body, in particular it cancorrespond to the maximum height of the third fitting body.

In a further preferred embodiment of the scaffolding system, the thirddecking profile is shorter than the second decking profile. The heightof the decking profile is preferably lower the shorter the deckingprofile. In this way, the scaffolding system can be designed to beparticularly weight- or load-effective.

The object according to the invention is further solved by a method formanufacturing a previously described scaffolding system, comprising themethod step:

-   A) Fastening, in particular in the same way, preferably welding, of    the first decking profile to the first fitting body.

Preferably, the method comprises the following additional process step:

-   B) Fastening, in particular in the same way, preferably welding, of    the second decking profile to the second fitting body.

Further preferably, the method comprises the following additionalprocess step:

-   C) Fastening, in particular in the same way, preferably welding, of    the third lining profile to the third fitting body.

Process steps A), B) and C) can be carried out in any order.

Further preferably, the method comprises the following process step:

-   D) Reversibly detachably arranging of the first fitting on the first    horizontal bar.

Previously, simultaneously or subsequently, the second fitting (and/orthe third fitting) can be reversibly releasably arranged on the firsthorizontal latch.

Further advantages of the invention can be seen from the description andthe drawing. Likewise, the above-mentioned and the still furtherelaborated features can be used according to the invention in each caseindividually or as a plurality in any desired combination. Theembodiments shown and described are not to be understood as a conclusivelist, but rather have an exemplary character for the description of theinvention.

FIG. 7a shows a side view of a scaffold decking according to FIG. 4, butwith a different connection of the third decking profile to the fitting,whereby this is in particular identical to the connection shown in FIGS.5a and 6 a.

FIG. 7b shows a side view of the scaffold covering according to FIG. 7awithout hidden edges.

FIG. 1a shows a first fitting 10 for connection to a first horizontalledger of a scaffold. The first fitting 10 has a fitting body 12. Thefitting body 12 can be made of metal, in particular sheet metal. Supporthooks 14 a, 14 b are provided for supporting the first fitting 10 on thefirst horizontal ledger. In the assembled state of the fitting 10, thefirst horizontal bar is overlapped by at least one gripping hook 16 a,16 b, in particular by two gripping hooks 16 a, 16 b. A bracket 18arranged movably relative to the fitting body 12 secures the firstfitting 10 against lifting off, for example in the event of a gust ofwind.

The first fitting 10 has two corner regions 20 a, 20 b into which adecking profile can be received. The corner regions 20 a, 20 b each havesurfaces 22 a, 22 b, 22 c, 22 d formed at right angles to one anotherthat both facilitate receiving the decking profile and allow effectiveload transfer from the decking profile into the first fitting 10. Thecorner portions 20 a, 20 b may be connected to a front face 24, thefront face 24 preferably being connected to the face 22 b and/or 22 d atright angles.

FIG. 1b shows a front view of the first fitting 10 according to FIG. 1a. It can be seen from FIG. 1b that the front panel 24 has downwardlytapered side panels 26 a, 26 b to save weight. The gripping hooks 16 a,16 b are formed offset from the horizontal center of the first fitting10 so that another identical fitting can be arranged on the same firsthorizontal bar. The load capacity of the gripping hooks 16 a, 16 b isincreased by at least one stiffening web 28 a, 28 b, 28 c, 28 d,preferably several stiffening webs 28 a-28 d.

FIG. 2 shows a first framework decking 30 with a first fitting 10according to the first fitting 10 shown in FIGS. 1a and 1b , which isfixedly connected to a first decking profile 32, i.e., not detachablewithout tools. The vertical maximum height H32 of the first deckingprofile 32 exceeds the vertical maximum height H12 of the first fittingbody 12, in particular by a factor max Kh=1.5 to 2.5.

FIG. 3 shows a second framework decking 34 with a second fitting 10′according to the first fitting 10 shown in FIGS. 1a and 1b , which isfixedly connected to a second decking profile 36. The vertical maximumheight H36 of the second decking profile 36 exceeds the vertical maximumheight H12 of the second fitting body 12′, in particular by the factormid Kh=1.1 to 1.5.

FIG. 4 shows a third framework decking 38 with a third fitting 10″according to the first fitting 10 shown in FIGS. 1a and 1b , which isfixedly connected to a third decking profile 40. The vertical maximumheight 1140 of the third decking profile 40 exceeds the vertical maximumheight H12 of the third fitting body 12″, the latter preferably beingcoordinated with the maximum height H40 of the third decking profile 40.

As exemplarily shown in FIGS. 2 and 3, the decking profile 32, 36 can berounded or have a rounding R on its underside towards the fitting 10,10′ in order to avoid a notch effect when the framework decking 30, 34is loaded.

The scaffold decks shown in FIGS. 2 to 4 each form, individually ortogether, a scaffolding system. The same fittings 10, 10′, 10″ are usedwithin this scaffolding system, so that the scaffolding system can becompleted in a particularly cost-effective manner. The scaffold decks30, 34, 38 are preferably connected to the fittings 10, 10′, 10″—asshown in FIG. 4 with reference signs—by means of connections ofidentical type and manner (e.g. three connection points arranged in anL-shape for bolting, riveting, toxing or welding on side surfaces of thefittings 22 a and 22 c), in particular by means of welded connections 42a, 42 b, 42 c. The lower the maximum height H₃₂, H₃₆, H₄₀ of theframework planks 30, 34, 38, the shorter they are preferably formed (seeindicated lengths L₃₂, L₃₆ and L₄₀). Since scaffold decks 30, 34, 38 ofdifferent lengths L₃₂, L₃₆, H₄₀ preferably do not all have the samelarge maximum height H₃₂, H₃₆, H₄₀, significant weight, energy used andcosts are saved during transport and assembly of the scaffolding system.

FIGS. 5a and 5b show a first framework covering 30′ which corresponds tothe first framework covering 30 according to FIG. 2 except for thedifferently formed welded joints 42 d, 42 e (in particular second typeof welding).

FIGS. 6a and 6b show a second framework covering 34′ which correspondsto the second framework covering 34 according to FIG. 3 except for thedifferently formed welded joints 42 d, 42 e (in particular second methodof welding according to FIGS. 5a and 5b ).

FIGS. 7a and 7b show a third framework facing 38′ which is similar tothe third framework facing 38 according to FIG. 4 except for thedifferently formed welded joints 42 d, 42 e (in particular second way ofwelding according to FIGS. 5a and 5b or FIGS. 6a and 6b ).

Taking a synopsis of all figures of the drawing, the invention relatesin summary to a scaffolding system with at least one scaffolding decking30, 30′, 34, 34′, 38, 38′. The scaffolding decks 30, 30′, 34, 34′, 38,38′ preferably have identical fittings 10, 10′, 10″ which are connectedto decking profiles 32, 36, 40 of different heights, in particular in anidentical manner. Particularly preferably, the scaffolding system has atleast two scaffold deckings 30, 30′, 34, 34′, 38, 38′, each havingidentical fittings 10, 10′, 10″, but decking profiles 32, 36, 40 withdifferent maximum height H₃₂, H₃₆, H₃₈, wherein further preferably thelength L₃₂, L₃₆, L₄₀ of the decking pro-file 32, 36, 40 with lowermaximum height H₃₂, H₃₆, H₃₈ is shorter than in the case of the deckingprofile with greater maximum height H₃₂, H₃₆, H₃₈.
